Chile consults on corporate tax rate implementation circular

Seven draft circulars are open for comment

The Internal Revenue Service (Servicio de Impuestos Internos, SII) says the first six draft circulars remain open until 17 November, while a separate draft on Tax Code information powers remains open until 18 November. The drafts follow prior review by the Tax Council and are proposed administrative instructions rather than final binding circulars.^[1]

The corporate circular addresses a staged enacted rate reduction

Law No. 21,850 reduces the First Category Tax rate for taxpayers in the general or partially integrated regime from 27% to 23% in stages. The SII’s implementation material specifies rates of 25.5% for tax year 2028, 24% for tax year 2029 and 23% for tax year 2030. The consultation notice says the corporate draft also addresses eligibility, the application of reductions to provisional monthly payments and the relevant timing.^[1][2][3]

The consultation does not accelerate the enacted timetable

The consultation is an opportunity to raise practical questions about the staged rate and payment calculations before the SII finalises its instructions. It is not an immediate November rate change. Groups should continue applying the enacted law and current SII instructions, identify the tax year and regime of each Chilean entity, and update forecasts and instalment calculations for the relevant periods when the final circular is issued.^[1][2][3]

Other measures require separate analysis

The same consultation round also covers capital-gains taxation, the DFL2 housing regime, a temporary VAT exemption for new homes, donations and exporter rules on cessation. Those topics are not treated as settled by this focused corporate-rate brief. The complete corporate draft text was not readable in the materials opened for this review, so detailed interpretations, shareholder-credit effects and taxpayer-specific conditions remain to be checked against the final circular.^[1]
